Observable (?) cosmological signatures of superstring models

The different couplings of the dilaton to the U(1) gauge field of heterotic and Type I superstrings may leave an imprint on the relics of the very early cosmological evolution. We discuss the possibility of discriminating between the two models through cross-correlated observations of cosmic magneti...

We discuss the possibility of discriminating between the two models through cross-correlated observations of cosmic magnetic fields and primordial gravitational-wave backgrounds.
